In the UEFI Shell, the SmbiosView command can retrieve and display the SMBIOS data. [15] [16] One can often enter the UEFI shell by entering the system firmware settings, and then selecting the shell as a boot option (as opposed to a DVD drive or hard drive).
On MS-DOS, the command is available in versions 2 and later. [8] Paragon Technology Systems PTS-DOS 2000 Pro also includes a vol implementation. [9] The Windows dir command also displays the volume label and serial number (if it has one) as part of the directory listing. The command is also available in the EFI shell. [10]
The Windows boot manager is located at the \EFI\Microsoft\Boot\ subfolder of the EFI system partition. [23] On Windows XP 64-Bit Edition and later, access to the EFI system partition is obtained by running the mountvol command. Mounts the EFI system partition on the specified drive. Available on Itanium-based computers only. [24]
A defining feature of the fish shell is built-in syntax highlighting, As the user types, text is colored to represent whether the input is a valid command or not (the executable exists and the user has permissions to run it), and valid file paths are underlined. [50]
Therefore, shell builtins are usually used for simple, almost trivial, functions, such as text output. Because of the nature of some operating systems, some functions of the systems must necessarily be implemented as shell builtins. The most notable example is the cd command, which changes the working directory of the shell.
The command is also available in the open source MS-DOS emulator DOSBox and in the EFI shell. [7] It is named chdir in HP MPE/iX. [8] The command is analogous to the Stratus OpenVOS change_current_dir command. [9] cd is frequently included built directly into a command-line interpreter.
The original motivation for EFI came during early development of the first Intel–HP Itanium systems in the mid-1990s. BIOS limitations (such as 16-bit real mode, 1 MB addressable memory space, [7] assembly language programming, and PC AT hardware) had become too restrictive for the larger server platforms Itanium was targeting.

KornShell complies with POSIX.2, Shell and Utilities, Command Interpreter (IEEE Std 1003.2-1992.) Major differences between KornShell and the traditional Bourne shell include: job control, command aliasing, and command history designed after the corresponding C shell features; job control was added to the Bourne Shell in 1989 [9]
